Abstract
In a process for the production of a plate, in particular a motor vehicle licence plate, in which at least a layer sequence forming an electroluminescence flat capacitor (4, 5, 6, 7) and a reflection film (10; 10′) are applied to a carrier (1), a reflection film (10; 10′) is selected whose reflection value is higher than the maximum value permitted by statute, and said reflection value is reduced by further production steps to such an extent that it is below the maximum value permitted by statute.

) is higher than the maximum statutory permissible value, and said reflection value is reduced by further production steps to such an extent that it is below the maximum statutory permissible value, characterised in that the reflection film (10′
) includes a layer (16) which is opaque in relation to the light of the electroluminescence flat capacitor (4, 5, 6, 7) and that the further production steps involve providing the reflection film (10′
) with a grid raster of holes in which the size and surface density of the holes (19) are so selected that on the one hand the reflection value of the reflection film (10′
) averaged in relation to surface area comes to lie below the maximum value permitted by statute and on the other hand the brightness of the light passing through the openings from the electroluminescence flat capacitor (4, 5, 6, 7) averaged over the surface area exceeds the minimum value prescribed by statute.
